The MDIS acceptance test is the government evaluation of the MDIS system availability, performance, and functionality. The test is performed over a period of 30 days and is composed of three test scenarios which are: (1) System/component availability test, (2) component performance test, and (3) system integration test. A test protocol describes each test in detail, as well as describing the actions of the vendor and test teams during the test period. Fifty-six test modules were derived directly from the performance criteria specified in the MDIS contract. These test modules are used by the test team members to evaluate the MDIS system. A database is used to compile the results of the acceptance test for management and comparison of multiple MDIS site results.
